Section 2 — Installation
1. Place the Analog Output Module on the I/O Module Extender
(064834), and select 100% Color Bars as the Program and Preview
switcher output. (You may use the internal signal for this adjustment
which is accessible through the Configuration [INPUTS] menu.)
2. The gain adjustment trimpots are accessible with the DAC mezzanines
installed on the Analog Output Module. Connect a waveform monitor
or oscilloscope to the Analog Output(s). Terminate the scope or
monitor’s inputs in 75 Ohms. A component waveform monitor is
convenient in that all three output channels can be observed
simultaneously, but it is only necessary to observe one at a time.
3. Adjust the gain controls to match the waveform for the desired format
shown in Figure 2-26 for color difference or Figure 2-27 for RGB.
NOTE: In RGB formats, the gain controls are somewhat interactive. For best
results, adjust Y gain while observing green output such that the white color bar
is at specified level. Then observe red output and adjust R-Y gain for equal level
bars having red content; similarly, observe blue output and adjust B-Y gain for
equal level bars.
Effects Send Option
The Effects Send option consists of the Effects Send Module which resides
in slot A11. When the effects send is used, the Aux Bus outputs of Serial
Output Module 2 (slot B11) become the outputs of the Effects Send option.
This allows A video and key signals (any two signals) in an M/E to be
routed outside of the switcher for processing by external devices and then
brought back into the same M/E for mixing and output. The Effects Send
functions require software set ups in the Configuration menus (See
Section 3 of the Reference Manual).
